This is a wallet specially designed to be worn on the
owner's belt, while still being highly resistant to theft.

This is accomplished as follows:

First, worn on the belt directly, is a slim metal mounting
bracket that the belt slides through, and which has some
sort of slightly protruding
component which the wallet
clips to. Since the bracket has a loop, not a clip, the only
practical way to get it onto or off of the belt is to remove
the belt from the user's waist, or cut the belt.

Second, the wallet itself has a clip of some sort which
connects to the bracket, and a fingerprint sensor which
releases this clip.

Third, the wallet is made difficult to open when it's clipped
to the belt.

Simply stuffing both trouser pockets with what looks like bunches of human hair wearing curling rollers is hard to beat when it comes to taking attention away from any wadges of cash you might want to transport.

8th, I intentionally described the idea in a minimal
fashion, so that numerous other security features could
be added, but wouldn't be required. Nothing prevents
you from ordering a version of this wallet which looks like
an ammo clip. Especially considering that there now
exist fingerprint scanners which use ultrasound, instead
of optics, and are capable of working through opaque
materials, including metal.

2fries, I know this "cash" stuff is supposed to be going out
of style, but yes, people still carry moderate amounts of
it with them.

Many of the new chip card readers here in the US are
disgustingly slow, to such a degree that coins and pieces
of paper are faster.

Of course, if you are a cashless person, you could get a
card-only version of it.

xenzag, that wouldn't work, people will assume that it's a
wig, not a scalp.

Indeed; but the psychology involved is a little different.

"Hmm, my potential victim is carrying a .50 AE Desert Eagle and spare clips. Well, maybe one of those clips is actually a disguised money clip. Thing is, even if I do grab the right one, I can run at maybe 8 m/s, and those rounds travel at 400m/s. So what's the chance of me getting out of accurate range before I get hit, assuming that he can get off eight rounds in the first four seconds ? No, don't like the math ..."

Hey, I'll have you know I've faced down some pretty streetwise rabbits in my time.

I know what you're thinking: "Did he fire one shot or only none?" Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being this is a .22 Webley, the most powerful air rifle in the this village, and would blow your head clean off, you've got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?
